Hence it will never be accessible. If class B inherits class A privately. If class A has add function with protected access, and few other members in public.
None other than class members can access name, also, neither the constructor nor the disp function are accessing the variable name. Variable name will never be used. All the data members are counted to calculate the size of an object of a class.
Here, the member function is private so there is no way that it can be overridden. Which member will never be used from the following class?
Constructor is not having any default arguments hence no default value will be given to any parameters. The friend function of class B will not be able to access private members of class A.
Only thing is, they must be accessed from members of class only. The private members are most secure in inheritance. Which data member in following code will be used whenever an object is created? Hence these two will always be used with each object creation. The constructor is using a static member to keep the count of the number of objects created.
It is not only about the function addbut all the members of class A will become private members of class B. Whenever an object will be created, the constructor will be called. Which access specifier should be used so that all the parent class members can be inherited and accessed from outside the class?
Which member can be considered most secure in the code below? Private member functions can be overloaded. Class B object will not be able to call any of the private, protected and public members of class A. In turn, no objects will be created and the class can only be used for inheritance. The private members will not be inherited.
All the constructors must be made private. This will restrict the subclasses to implement those members. Since B is inheriting class A privately, the members will become private in class B. Only integer values must be passed to the constructor if we need the sum as output, otherwise if float values are passed, type mismatch will be shown as error.
Will the friend function be able to access the private member of class A? This is done because the variable c is static and hence the value will be common for all the objects created.
The private functions can also be overloaded. And class B has a friend function.
Which among the following is true? Then class B inherits class A privately. The implicit constructor will always be public.
Hence all the data size will be added. Which option is false for the following code? This is because, overriding means a function with same name in derived class, gets more priority when called from object of derived class.Which access specifier is used when no access specifier is used with a member of class (java)?
c Explanation: Protected access is used to make the members private. But those members can be inherited. All the data members are counted to calculate the size of an object of a class.
The data member access specifier doesn’t play any role. Object Oriented Programming Questions and Answers – Private Access Specifier Posted on December 28, by Manish This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on “Private Access Specifier”.
Protected access specifier prevents its data members and methods accessing from other classes directly. These data members and methods can only be accessed in sub classes or the other classes through the friend function.
Additionally protected access specifier allows friend functions and classes to access these data members and functions. Protected data members and functions can be used by the class derived from this class.
Answer: Use of public private and protected access specifiers in C++ is to control the access/visibility of member data and functions out of a class. It all depends upon requirement when we design a class, what access level to fields and member functions, we want to provide in a class with the use of public private and protected specifiers.
Access Specifier or Modifier in C# On By. Protected: protected member can be access within containing classes and Derived classes. if you don't write any access-specifier in program then it will be internal by default in .Download
